Abstract
We present a multiwavelength mode-locked fiber ring laser incorporating two semiconductor optical amplifiers (SOAs) and a segment of dispersion-compensating fiber (DCF). One SOA is mode-locked by an injected external optical signal and act as loss modulator and assistant gain medium. The other SOA is not modulated by injected signal and only severs as gain medium. Two SOAs synchronously provide enough cavity gain for high repetition rate multiwavelength oscillation. A segment of commercial DCF is employed to introduce intracavity dispersion and functions as a self-tuned comb filter. Our laser source can generate 16 synchronized wavelength channels, each mode-locked at 10 GHz. 16 wavelengths from 1581.96 to 1597.52 nm is with a power deviation of about 4 dB and the mode-locked pulse average width is 39 ps. Oscillation wavelengths can be smoothly tuned to appointed wavelengths and the output power is rather stable.
